What is Visible Light?
"Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light." -http://science.hq.nasa.gov/kids/imagers/ems/visible.html
